CVSS: 9.0EPSS: 0%CPEs: 33EXPL: 0CVE-2020-25719 – samba: Samba AD DC did not always rely on the SID and PAC in Kerberos tickets
https://notcve.org/view.php?id=CVE-2020-25719
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. Se encontró un fallo en la forma en que Samba, como controlador de dominio de Active Directory, implementaba la autenticación basada en nombres de Kerberos. El AD DC de Samba, podía confundirse sobre el usuario que representa un ticket si no requería estrictamente un PAC de Kerberos y siempre usaba los SIDs encontrados dentro. • https://bugzilla.redhat.com/show_bug.cgi?id=2019732 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2020-25719.html https://access.redhat.com/security/cve/CVE-2020-25719 • CWE-287: Improper Authentication CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2021-3744
A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. Se ha encontrado un fallo de pérdida de memoria en el kernel de Linux en la función ccp_run_aes_gcm_cmd() en el archivo drivers/crypto/ccp/ccp-ops.c, que permite a atacantes causar una denegación de servicio (consumo de memoria). Esta vulnerabilidad es similar a la anterior CVE-2019-18808 A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to cause a denial of service. • http://www.openwall.com/lists/oss-security/2021/09/14/1 https://bugzilla.redhat.com/show_bug.cgi?id=2000627 https://github.com/torvalds/linux/commit/505d9dcb0f7ddf9d075e729523a33d38642ae680 https://kernel.googlesource.com/pub/scm/linux/kernel/git/herbert/crypto-2.6/+/505d9dcb0f7ddf9d075e729523a33d38642ae680%5E%21/#F0 https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7BLLVKYAIETEORUPTFO3TR3C33ZPFXQM https: • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2021-3602
An information disclosure flaw was found in Buildah, when building containers using chroot isolation. Running processes in container builds (e.g. Dockerfile RUN commands) can access environment variables from parent and grandparent processes. When run in a container in a CI/CD environment, environment variables may include sensitive information that was shared with the container in order to be used only by Buildah itself (e.g. container registry credentials).

https://notcve.org/view.php?id=CVE-2021-3733
There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. Se presenta un fallo en la clase AbstractBasicAuthHandler de urllib. Un atacante que controle un servidor HTTP malicioso al que se conecte un cliente HTTP (como un navegador web), podría desencadenar una Denegación de Servicio por Expresión Regular (ReDOS) durante una petición de autenticación con una carga útil especialmente diseñada que sea enviada por el servidor al cliente. • https://bugs.python.org/issue43075 https://bugzilla.redhat.com/show_bug.cgi?id=1995234 https://github.com/python/cpython/commit/7215d1ae25525c92b026166f9d5cac85fb https://github.com/python/cpython/pull/24391 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://security.netapp.com/advisory/ntap-20220407-0001 https://ubuntu.com/security/CVE-2021-3733 https://access.redhat.com/security/cve/CVE-2021-3733 • CWE-400: Uncontrolled Resource Consumption •

A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. Se ha encontrado un fallo en python.
